What is a battery transient response?lithium boat batteries Production

　　, Battery discharge under a relatively full charge. The previous curve indicates a discharge process. At this time, the voltage is relatively low, and then the load is removed. At this time At this time, because everyone thinks that the load removal current becomes 0, did the voltage at this time return to the voltage with a current of 0? No. It returned slowly, it took a long time to go back, everyone saw this curve. Everyone's usual experience can also prove this, that is, after a battery discharge, then you remove the load. Its voltage is constantly changing. So how long does this voltage change? It is about 1600 seconds at this point, and basically it must be stabilized until 3500 seconds, about 2000 seconds, to stabilize. This is a discharge of voltage from 3.8V to 3.9V, which means the battery This is the battery. It's not full.

　　According to the case that the battery just introduced just now, that is, when the battery capacity is large, the internal resistance of the battery is relatively small at this time. When the battery internal resistance is relatively small, it recovers it. Essence The following picture can see that the voltage here is relatively low. From about 3.3V, after a period of time, this time is also very short, because when the lithium battery voltage is relatively low, put it for a while for a while Electricity is close to the minimum capable voltage that can be accepted by the 3.2V system. At this time, if the discharge is stopped, how long does it take to return this voltage? Basically, it takes longer, such as more than 3000 seconds to stabilize the voltage. So during this time, its voltage is not stable enough, but there is no load, the current is always 0. At this time, you can read the voltage, the voltageIt has been changing. What is the corresponding capacity percentage? At this time, an error will occur, that is, the battery transient response.
